A few weeks ago I've upgraded my pc with some new components including 5x PC CoolerMaster SickleFlow 120mm coolers which, according to specs, should run at 2000 RPM, but accorting to 2 monitoring softwares they aren't doing so. Also, my other Artic Cooling F9 90mm cooler which is mounted on the rearside seems to be woriking properly at it's 1900 RPM.

For the record : 1x90mm + 3x120mm coolers are connected directly into the Motherboard and 2x120mm are connected to the power supply via 3pin to molex adapters. Edit : All of these coolers don't have RPM control only 1 standard setting

My question is, what will it take to make the other 5 coolers to function properly at their 2000RPM specification ?

Here is a photo of monitoring software readings :

Do you have all the fan controls set to "off" in the BIOS? If so, they should be running full speed. Otherwise, plug them directly into the PSU and they should go full speed (but you can't monitor them).

And how can I check if the Fan Control feature is on or off ? I use the 128M bits AMI UEFI BIOS
